Forest Circles, Natural Circular Features Resulting From Self-Organizing Processes

Forest Circles, Natural Circular Features Resulting From Self-Organizing Processes

Natural processes, other than impacts, can also cause circular
features seen in aerial photography and other imagery. Forest
circles are an example of a circular feature create by the
interaction of geology with plants. Go read:
